Rhino Hanging (Tabs)

Sometimes when going out of detailed view in a viewport on a layout tab, the tabs at the bottom of the screen no longer work, i.e. Perspective, Top, Right, Left, Layout, etc. I have to restart Rhino for them to work again? I’m on the latest version and this has always happened. Is this there a way to fix this or is this a bug?

Please run the Rhino SystemInfo command and return the results in a reply.

Hey John,

Also I noticed when running SystemInfo the Physical RAM is in scientific notation. This should probably be changed in v8.

My guess is because you’re running a “hybrid” laptop unplugged from power, you are not using your NVIDIA card.

Plug-in to power and make sure your hybrid lsptop is set up correctly:

Any luck?


Thanks for the quick feedback. Ya I know all about the 2 GPU’s. Rhino is using the NVIDIA GPU. Any other ideas?

In Windows Control Panel > Power Options > are you set for High Performance for both plugged in and on battery?

No it was on balanced so I changed it to High Performance. What’s interesting is the only setting that changes regarding this issue is the display adapter, however, the Intel adapter is what is showing. The NVIDIA doesn’t appear at all in the power settings…odd. The max processesor state was set to 100% for both battery and plugged in. Here are screenshots of both balanced and max performance. Since I changed it to high performance, I’ll let you know if this issue happens again. I wouldn’t think that this would affect the tabs; maybe make them slower if at all noticeable, but not hang.

If Rhino’s Options > View > OpenGL shows the NVIDIA card, then you’re probably okay.

You may have to create your own Windows power profile to select ONLY the NVIDIA for best performance.
I don’t know why Lenovo doesn’t do that for you.

Laptops are a big performance compromise.
That’s why we try to get people to choose a battery eating “Mobile Workstation” or desktop. The hybrid laptops (dual GPUs) are a further compromise. The laptops/notebooks with only Intel GPUs are refered to as “Craptops” around here.

OpenGL shows this:
NVIDIA Corporation
OpenGL version: 4.6.0 NVIDIA 517.66
Render version: 4.6
Shading Language: 4.60 NVIDIA
Driver Date: 10-19-2022
Driver Version:

Maximum Texture size: 32768 x 32768
Z-Buffer depth: 24bits
Stencil depth: 8bits
Maximum Viewport size: 32768 x 32768
Total Video Memory: 4 GB

I created my own power plan and still NVIDIA did not show up in the options. Only the Intel video card did.

This is a workstation laptop so it has an Intel i9-11950H CPU with 132GB of RAM so believe me it can drain the battery.
